Abstract

A distinctive characteristic of the reliquefaction behavior of soils is that there are instances where the phenomenon of a sharp decrease in liquefaction resistance occurs in spite of increases in soil density caused by drainage of water after liquefaction. This fact points to the existence of factors other than density that sway the liquefaction resistance of soils. The current paper demonstrates that, in fact, anisotropy is an important factor influencing liquefaction resistance. This is made clear through the results of systematic triaxial shear tests, which show that the higher the level of developed anisotropy, the lower the liquefaction resistance. In the process of verifying the above, we found that continuous and orderly changes in anisotropy are repeated with dizzying rapidity during liquefaction.
